MATTRESS-FILLING IvIACI-LINE VIIT'H DOUBLE ROTARY BEATER.

Application filed, July 28,

T all whom it may concern:

Be it known that I, PHILLIP BAKER, a subject of Lithuania, residing at Malden, in the county of Middlesex and State of Massachusetts, have inventednew and useful Improvements in MattressFilling Machines with Double Rotary Beaters, of which the following is a specification.

This invention relates to a machine for filling mattresses with down, floss and the like, and while the machine is particularly adapted for that purpose, the same may also be utilized for filling other articles, such as pillows, comforters and the like with floss, down or feathers.

The machine of this invention is an improvement upon a mattress filling machine for which U. S. Letters Patent No. 1,4c29,998, issued to me Sept. 26, 1922. The machine of this application has for its object to thoroughly beat up and circulate the filling ma.- terial prior to the time when the machine is being used to fill the mattress, and after the beating up and circulationof the filling material has been completed, the machine may.

be quickly and easily changed to fill a mat tress with the filling material as in the machine of my invention as set forth in said application for Letters Patent. The machine is similar to the machine of said application but differs therefrom in the mechanism for beating up the floss or other filling material, the object being to more thoroughly perform this operation and to this end primarily the invention resides in the beating up mechanism which consists of a pair of rotary beaters positioned adjacent to each other and preferably having the arms of one beater projecting between two adjacent arms of the other beater. 7

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claim thereof.

Referring to the drawings:

Figure 1 is a front elevation of the machine partly broken away and shown in section.

Fig. 2 is a sectional plan taken on. the line 22 of Fig. 1.

Fig. 3 is a sectional elevation of a portion of the mechanism particularly illustrating the beater mechanism.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is a receptacle for fill- 1922. Serial No. 578,218.

. ing material, the same consisting of a cylindrical base portion-6, a conical intermediate portion 7 increasing in' diameter from the bottom to the top thereof and a conical portion '8 decreasing in diameter from the bottom thereof to the top of the receptacle. At the bottom of the conical portion 7 is a grate 9 andunde'rneath this grate is a pit adapted to receive refuse material and this pit is provided with a door 10 whereby'said refuse material may beremoved from the pit. A

door 11 is provided in the conical portion"! of the receptacle and this door is provided with a hopper 12 having a cover 13 hinged to the door 11., Filling material may be introduced into the receptacle 5 through the hopper 12. A screen 1 1 is provided in the top of the conical portion 8 of the receptacle. A. circulating fan 15 is connected by an intake pipe 16 to the lower part of the conical portion 7 and a return pipe 17 connects said fan to the upper portion of the receptacle.

In the present embodiment of my invention the return pipe is connected to the conical portion 8 and extends downwardly therefrom and entirely through the receptacle 5 projecting outwardly therefrom to form aprojecting open, outer end 18. A portion 19 of the return pipe 17 which extends through the receptacle 7 has an opening 20 therein which leads into the recep-,

tacle 5. A damper 21 is fast to a shaft 22 which extends transversely of the receptacle 7 and is provided at its outer end with an arm 23 constituting a handle whereby the damper 21 may be rotated to open the portion 19 of the return pipe or to close the same. When the damper 21 is positioned as illustrated in the drawings, the opening 20 is closed and when thedam-per is turned upwardly so that theopening 21 opens into the receptacle 5, then the pipe 19 is closed by said damper.

An annular flange outer end of the projecting portion 18 of the return pipe 17- and this portion of the return pipe constitutes a nozzle to which the open end portion of the mattress is fastened while the filling operation is in process.

The material used for filling the mattress, such as silk floss, is first thoroughly beaten up in the receptacle 5 and this is accomplished by means of an agitating device or heater 25 consisting of a pair of rotary members 26 and 27. The rotary member 26 con- 24 is provided on the sists of a shaft. 28 with arms 29projecting radially therefrom. The rotary member 27 consists of a shaft 30 and arms 31 projecting radially therefrom. The shafts 28 and 30 are rotatably mounted in suitable hearings in the portion 7 of the receptacle and these shafts lie in approximately the same horizontal plane and project outwardly from the receptacle at the rear side thereof, the shaft 28 having a pulley 32 fast thereto and connected by a belt 33 toa pulley 34 which is fast to the shaft 30. The shaft 30 has another pulley 35 fast thereto which is connected by a belt 36 to a pulley 37 fast to the shaft 38 of an electric motor 39. Another pulley 40 fast to the motor shaft 38 is connected by a belt 41 to a pulley 42 which drives the fan 15. A damper 43 is provided in the pipe 16 adjacent the receptacle 5 whereby said pipe may be opened or closed. Itwill benoted thatthe radial arms 29 of the rotary beater member 26 project between adjacent arms 31 of the rotary beaterjmember 27. Inclined chutes 44 and 45 are fastened tov the opposite sides of the receptacle 5 and act as guide chutes to guide the material intothe beaters 26 and 27 respectively,

j the lower ends of said chutes terminating approximately in the plane of the shafts 28 and 30. The chute 45 is provided with an opening 46 through which the filling material passes into the outlet pipe 16,

It will be noted that while the rotary beater members 26 and 27 rotate in the same direction, the radial arms 29 move downwardly and the radial/arms'31 move upwardly during that portion of the rotation of the respective members 26 and 27 wherein these arms project between each other so that the rotary beater member 26 acts to carry the filling material upwardly from the chute 44 over and downwardly onto the rotary beater member 27, which thereupon takes the floss or other filling material and carries it toward the opening 46 and from thence it is carried by the suction in the pipe 16 to the circulating fan 15, thus thoroughly mixing and beating up the filling material.

The general operation of the mechanism hereinbefore specifically described is as follows: Assuming the filling material to have been inserted within the receptacle 5 through the hopper 12 and that the mattress to be filled is fastened in a manner. well known to those skilled in the art to the outer end of the portion 18 of the return pipe 17; the

, first operation to be performed is to beat up the, floss with the rotary beater members 26 and 27 and this is done by first closing the damper 43 and closing the opening 20 by means of the damper 21. After the floss has been thoroughly beaten up the damper 43 is opened and the damper 21 isturned across the portion 19 of the pipe 17, and the fan will then operate to cause the silk floss to circulate and also to be further beaten up, the circulation of the floss taking place from the receptacle 5 through the pipe 16 through the blower 15 and through the return pipe 17 and through a portion of the pipe 19 and outwardly therefrom through the opening 20 into the receptacle again. This circulation of the material continues until, by inspection through a hopper 47, the silk floss is found to be in proper condition to be fed into the mattress, whereupon the damper 21 is turned to close the opening 20 and the blower draws the floss out of the receptacle 5 and forces it through the return pipe 17 and through the'portion 19 of said return pipe out of the outlet end 18 of said pipe and into the mattress. As soon as the mat tress is filled, the operation hereinbefore described is repeate It will be understood that the shafts of the circulating fan and of the rotary beater member 27 are rotated by the electric motor 39 through the belts 41 and 36 respectively and that the rotary beater 26 is rotated by the belt 34 which connects the pulley 33 to the pulley 32.

I claim: I

A machine for filling mattresses and the like having, in combination, a receptacle for filling material, a circulating fan, intake and return pipes connecting said fan to said receptacle and a pair of rotary beater ele-' ments, each of said heater elements compris- 111g a rotary shaft and a plurality of radial arms thereon, said shafts lying in approximately the same horizontal plane, and a pair of oppositely disposed downwardly inclined chutes positioned on oppositesides respectively of said receptacle and terminating at their lower ends adjacent the outer ends of said rotary beater elements and approximately in said horizontal plane.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. I
